AIR cocaine oanaarine APPARATUS.

Application filed August 17, 1925. Serial No. 50,567. 'I

This invention relates to improvements in fans particularly oscillatingelectric cooling and heating fans, and it is the principal -ob ject ofthe invention to provide a fan in fan withthe casing in sectionaccording th form of coil in the casin which the cooling or heatingmedium Within a container is circulated around thefan by means of amotor driven pump.

Another object of the invention is the provision of a fan, of the abovetype equipped with ineans allowing'a raising and lowering of the fan toa certain degree within certain limits without interfering with itsoscillating movements.

A'still further object of the invention is the provision of amotoroperated fan equipped with a pressure valve for regulating the heatingcapacity. i

A still further object of this invention is the provision of a motoroperated fan en closed in a bi-partite housing of simple and.inexpensive construction yet durableand efficient'and allowing a readyinspection'and cleaning. j

It is, furthermore one of the objectsof my invention toprovide a fan,the heating or cooling medium of which is circulated my invention on anenlar ed scale.

Fig. 4 is a front elevationv of a-modified Fig. 5 is a. section on line5-5. of Fig. 4.

Fig. 6 is a. section on line 66 of Figure 4.

The fan constructed according to the invention as illustrated in thedrawing comprises a base 10 on feet 11 and which carries posts orstandards 12 between which is pivotally secured, as at 13, a support.carrying at one end a motor of any desired suitable type equipped withthe customary oscillating mechanism' within" a casing 14, having a stem14, turnably arranged in the support;

the motor shaft 15 carries a bevel gear 16 in mesh with a bevel gear 17on the shaft of a water pump within casing 18 which carries also anagitator 19, in the upper wall of a container 20 .or the like on thebase 10 and connected by a flexible connection 19 to the pump. Thefunction of the agitatoris to lnsure a thorough mixing of the fluid inthe container 20. The motor shaft 15 carries at itsend a suitablebearing 21 for the fan blade or blades 22.

A water circulating pipe or conduit 23 is guided about the fan in a.plurality of convolutions, one end of which has attached thereto anexhaust pipe 24 having a flexible pipe 24 attached thereto, the oppositeend of which enters the container 20 to return the cooling or heatingmedium contained therein to said container after the performance of itswork and .for this purpose is I equipped with a suitable nipple 25.

Fan and circulating pipe are surrounded by a. casing 26' open at therear and front,

and composed of two parts hinged, together as at 26, while a removablejoint 27 connects the. convolutions of pipes 23 and. 24 allowing aseparation of these, and the casing parts for inspection and cleaningpurposes.

The casing 26 and its contents may be elevated andlowered. above andbelow the horizontal by means of two separate stem portions having rightand left hand threads, re-

jspectively, indicated on the drawing 'by numeral 28, upon which isthreaded a-nut or adjusting sleeve/-31 which operates in the nature ofa. toggle joint. The upper end of the top stem 28 is secured to aso'cket 29 on the fan casing 26, while the lower end of the lowerstemi28 is provided with a roller 30 engaging a depression in the base10.

If desired or required the water contained in container 20 is heated bymeans of a heater 32, located near the bottom of the container andadapted to be attached to the source of electricity by the leads 33, 34leading to a suitable plug '35. In Qrder to relievethe pressure incasing 20 when the same rises beyond a predetermined degree, a reliefvalve 36 is shown at the top ofcontainer 20 adapted to operate a lever37 which is at o'neend engaged by the stemlof' valve 36, whileits otherend operates switch '39 in box, 40, adapted to connect or disconnect themotor 14, as the case may be fromthecircuit with which the switch is Iconnected by the leads 41,42.

The operation will be entirely clear from the above description andneeds no further explanation, and it is to be understood that suchchanges may be made in the construction of the fan, as shown anddescribed as an example of the many modifications of which it iscapable, such as come withinthe scope 'ofthe appended claims withoutdeparture from the spirit of the invention or the principle involved.

, Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

L -In a device of the class described, having a fan blade and a fluidcirculating pipe formed into a plurality of convolutions in two sectionsin the front and rear of said fan bladerespe'ctively, the combination ofa casing opened at the rear and front, said casing being composed oftwoparts hinged together at the top, and said hinge connection being formedwith a movable joint connecting the sections of said convolutions in thefront and rear of said fan blade.

2. In a device of the class described, having a fan blade and a fluidcirculating pipe formed into a plurality of convolutions in two sectionsin the front and rear of said In testimony whereof I have affixed mysignature.
